Seven Hills is located 34 kilometres west of the Sydney central business district in the local governement area of the City of Blacktown.
Prior to European settlement in the 1790s, the area now known as Seven Hills was originally settled and occupied for hundreds, if not thousands, of years by indigenous people who most probably would have identified with the Warmuli and Toogagal clans, of the Darug tribe.
The vicinity of Seven Hills was first visited by Europeans very early on in the settlement of the colony of New South Wales, possibly as early as April, 1788 by Arthur Phillip or more certainly by Watkin Tench in June 1789.
Matthew Pearce (1762-1831) was granted 160 acres (53 ha) in 1795, which he named after ‘Kings Langley Manor House’ in Hertfordshire, England, where he was said to have been born. This area became known as Seven Hills from 1800, beacuse he could see ‘seven hills’ from his home.
Seven Hills encompassed a much larger area and as late as 1900, landowners as far afield as the modern suburbs of Bella Vista, Glenwood and Parklea identified their properties as being located in Seven Hills. In the 1970s housing schemes excised land that was previously part of Seven Hills to create the suburbs of Lalor Park and Kings Langley.
The railway from Parramatta to Blacktown station was completed as a single line in 1860. A station master’s residence and siding were constructed near a level crossing at what was Toongabbie Road (later Seven Hills Road) in December 1863. A platform was built in 1869, and stops at the station were scheduled in the timetable from September of that year. The road bridge on Seven Hills Road across the railway line was constructed in 1975, replacing the level crossing.
